According to research reported at the 2019 Alzheimer’s Association International Conference, LGBT people are at greater risk for dementia than the general population. Correlates (and possible causation) among the current aging LGBT population are a greater likelihood of being alone, a greater probability of not having children and a greater prevalence of depression.
After adjusting for factors such as race, income and age LGBT people were 29% more likely to report confusion or a loss in memory.
Overall, researchers at University of California San Francisco polled 45,000 people, age 45 and older, across nine states. About 3% were queer. It is important to understand that the results (and sexuality) are self-reported. Moreover the 45-65 group may suffer from disparities in overall healthcare as they do not qualify for Medicare.
I have contacted the primary author for some additional information and will update accordingly.
